Hey. I am trying to get the different display modes working with my portege M400 laptop. Im running 2.6.32 with the toshiba_acpi module. the problem is that when i do:

echo "lcd_out:0;crt_out:1" > /proc/acpi/toshiba/video
cat /proc/acpi/toshiba/video

i get:
lcd_out: 1
crt_out: 0
tv_out: 0

I am following the guide at http://memebeam.org/toys/ToshibaAcpiDriver. Why does the state of the crt_out variable not change? the kernel file where this is handled is: kernel/drivers/portability/x86/toshiba_acpi.c

thanks in advance...

hmm ok i tried running xrandr and heres the output it sees:

Screen 0: minimum 320 x 200, current 1400 x 1050, maximum 2048 x 2048
VGA connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1024x768 60.0*
800x600 60.3
640x480 59.9
LVDS connected 1400x1050+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1400x1050 60.2*+ 74.8 60.0
1280x1024 85.0 75.0 60.0
1280x960 85.0 60.0
1152x864 75.0
1024x768 85.0 75.0 70.1 60.0
832x624 74.6
800x600 85.1 72.2 75.0 60.3 56.2
640x480 85.0 72.8 75.0 59.9
720x400 85.0
640x400 85.1
640x350 85.1
TMDS-1 disconnected (normal left inverted right x axis y axis)

so it appears that xrandr sees the VGA output to the TV. I am not sure whether or not it is mistaking the laptop display for VGA or not, but i THINK its talking about the TV that i have connected to the VGA port on my laptop. does anyone have any ideas what to try?
